SW RGBHV Series Switchers 1 Chapter One Introduction About the Switchers Features
Introduction, cont’d Introduction About the Switchers The Extron SW RGBHV series (figure 1-1) is a family of six RGB video switchers, some with audio, in an array of input and output configurations.
Features Audio switching models Inputs — These switchers input 2, 4, or 6 stereo audio signals, balanced or unbalanced, on 3.5 mm, 5-pole captive screw terminals. Outputs — The selected audio input is buffered and output, balanced or unbalanced, on a 3.5 mm, 5-pole captive screw terminal. Audio gain/attenuation — Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) via the RS-232 link or from the front panel, to be compatible with a wide range of line level (from -20 dBV to +4 dBV).
Introduction, cont’d Autoswitching mode — When autoswitching is enabled, the switcher continuously monitors all inputs and automatically switches to the highest-numbered input with video sync pulses present. If video is absent from all inputs, no input is selected. Operational flexibility — The operator can select the input and set the audio gain and attenuation for each input using the front panel buttons or via the switcher’s Remote port RS-232 link.
SW RGBHV Series Switchers 2 Chapter Two Installation Installation Overview Mounting the Switcher Cabling and Rear Panel Views
Installation, cont’d Installation Installation Overview Install an SW RGBHV Series switcher as follows: 1 Turn off the input and output devices, and unplug their power cables. 2 If desired, mount the switcher in a rack, under furniture, or through furniture. See “Mounting the Switcher”, below. 3 Connect the input and output devices to the switcher (see “Cabling and Rear Panel Views”, on page 2-7).
SW2 models 1. If rubber feet were installed on the bottom of the switcher, remove them. 2. Place the switcher on one half of the optional RSU 129 or RSB 129 1U (one unit high, 19" wide) rack shelf (part #60-190-01 or 60-604-02). Align the front of the switcher with the front of the shelf, and align the threaded holes on the bottom of the switcher with the holes in the rack shelf (figure 2-1). Use 2 mounting holes on opposite corners. False front panel uses 2 front holes.
Installation, cont’d SW4 and SW6 models 1. If rubber feet were installed on the bottom of the switcher, remove them. 2. Attach the rack mount brackets to the switcher with eight provided #8 machine screws, provided (figure 2-2).

Hold the switcher with attached brackets against the underside of the desk or other furniture. Mark the location of holes for screws on the underside of the desk. 3. Drill 1/4" (6.
Installation, cont’d Through-furniture mounting the switcher The switchers can be mounted through a desk or other furniture. The SW2 models require an optional through-desk mounting kit, part #70-077-02. The SW4 and SW6 models require the included through-desk and rack mounting bracket.

c. Tighten the screws. d. Replace the switcher on the underside of the surface (step 6). Cabling and Rear Panel Views All connectors are on the rear panel. The switcher can be connected to up to six RGBHV or component video devices and (audio models only) stereo audio devices, depending on the model. The video and/or audio output output is identical to the selected input; the switchers perform no sync or video format manipulation.
Installation, cont’d 2 Balanced or unbalanced audio input connections (SW2 RGBHV A, SW4 RGBHV A, and SW6 RGBHV A only) — Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each SW RGBHV Series switcher, but you must supply the audio cable. See figure 2-8 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 10k ohms.
Remote connection 5 Remote connector — Connect a host device, such as a computer or touch panel control, or a remote contact closure device to the switcher via this 9-pin D connector (figure 2-10) for remote control of the switcher. See chapter 4, “Remote Control”, for definitions of the SIS commands, details on how to install and use the control software, and information on how to construct a remote contact closure device.

SW RGBHV Series Switchers 3 Chapter Three Operation Controls and Indicators Switcher Operations Optimizing the Audio (SW2, SW4, and SW6 RGBHV A only) Troubleshooting — If No Image Appears
Operation, cont’d Operation Controls and Indicators The SW RGBHV family of switchers have 2, 4, or 6 input buttons and LEDs on the front panel. Audio models also have front panel configuration controls and LEDs. All models have an Auto/Manual mode selection switch on the rear panel. Figure 3-1 shows the front panel of an SW2 RGBHV switcher. Figure 3-2 shows the front panel of an SW6 RGBHV A switcher.
Audio controls and indicators 3 Audio configuration/save button and LED — The Audio button and LED enable the user to view and/or change the current audio level setting for each input. See “Audio gain and attenuation (SW2 RGBHV A, SW4 RGBHV A, and SW6 RGBHV A only)”, later in this chapter. 4 Down ( ) button and LED — The button is used to decrease the audio level for a selected input. The LED flashes each time the button is pressed to indicated a 1 dB decrease in the audio level.
. Operation, cont’d Switcher Operations The following paragraphs detail the power up process and provide sample procedures for selecting an input and viewing and adjusting the audio level. Powering on the switcher 1. Plug in the switcher. On all switcher models, power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks the front panel LEDs during the test.
The audio level can be adjusted from the front panel or by using Extron’s Windows-based control program. The switcher must be in normal (manual) mode. 1. Press and release an input button to select an input. 2. Press and hold the Audio Conf/Save button until the Conf/ Save LED begins to blink, then release the Conf/Save button. The +dB and –dB LEDs display the polarity (+ or –). The lit +dB LED indicates a positive (gain) level. The lit –dB LED indicates a negative (attenuation) level.
Operation, cont’d If the +dB and –dB LED are both lit they indicate 0 dB. Otherwise, you can determine the exact gain or attenuation using the following procedure. a. If one or more input LEDs are lit AND the +dB LED is/are lit, press and release the button repeatedly until the highest-numbered lit input LED goes out. Count the button presses. In this example, assume a value of +8 dB. It will take three presses of the button for the Input 1 LED to go out.
Audio level reset — single input Reset the audio level for an input to 0 dB as follows: The switcher must be in normal (manual) mode. 1. Press and release an input button to select an input. 2. Press and hold the Audio Conf/Save button until the Conf/Save LED begins to blink, then release the Conf/Save button. 3. Press and release the Input LEDs go off. 4. Press and hold the Audio Conf/Save button until the Conf/Save LED goes off. The and LEDs go off, and the selected Input LED lights. and buttons.
Operation, cont’d Troubleshooting — If No Image Appears 3-8 1. Ensure that all devices are plugged in and powered on. The switcher is receiving power if the front panel Power LED (if equipped) is lit. 2. Ensure an active input is selected on the switcher or that the switcher is in autoswitch mode. 3. Ensure that the proper signal format is supplied. 4. Check the cabling and make corrections as necessary. 5. Call the Extron S3 Sales & Technical Support Hotline if necessary.
